GLContextImpl/GLDrawableImpl: More fail-safe, cleanup, mark some methods final

GLContextImpl: Cleanup
  - release(): simplify the conditions
  - destroy(): allow locked twice before (destroy case)

GLDrawableImpl:
  - fail safe: swapBuffers
  - final methods: getFactoryImpl, toHexString, getGLProfile, getRequestedGLCapabilities,
                   getFactory, isRealized, lockSurface, unlockSurface
